Lower door molding needs to be replaced on one of my doors. Deciding whether to replace all 4 of them right now bc replacing 1 might look bad and the others may come off or just doing the one that fell off. What are your thoughts?

 

yea,they are starting to get punky on my car too. good news, all 4 were around 100 at the dealer, and in stock too. i thought that was pretty good, seeing that rubber bits can get spendy
